But what I want them to sound like is better...more transparent, less edgy, less noisy, slightly warmer in tonal balance, etc. I know these desires are vague, but I want them to sound as good as the best parts can make them.

Have you tried tube rolling? Tungsol top getter 5U4G is my favorite for transparent and open sound. I have not heard the latest 300B's, but the older ones I have tried do sound different. AVVT 300B C37 glass are me favorites, but rarely seen on the web these days. I think I tried two different 6EM7's on the Tektrons with little difference in sound quality. I know there are a number of different brands of 6EM7's out there. I also never tried any substitutes, like 6EA7 or 6GL7.
I admit I love tube rolling. Nothing like spending hours listening to music and fooling around with your gear.
The 'EM7s are a bit confusing in that apparently identical tubes are branded differently, so I now separate them by plate color and type...for instance gray/gray, gray/black, black/gray, black/black, black/black-Ts, etc. Have NOT formed any opinions on SQ.In 300Bs I have pairs of original Shuguang Treasures, new Psvane TII-series, Gold lion PX300Bs, new EMLs, used JJs, and a trio of Sophia Golden Princesses.
I have many different types and brands of 5U4Gs. The closest I can get to 'top getters' are two almost-identical ones with a D-shaped getter hanging from a wire off the top mica; they're branded Westinghouse and RCA. The most-complicated-looking 5U4Gs, with what appears to be reinforced top micas, etc., are two Sylvanias, one labeled 'U. S. NAVY C.H.S. SYLVANIA' and a commercial version labeled with more-modern-looking green ink.
Again, I haven't formed opinions of SQ on any of these; I just install them, make sure they work for a day or week, and put the next pair in.

It certainly sounds like you have the tube rolling covered. Now all you need is the time to do the listening.
Lights low, glass of wine in your hand, eyes closed - Nora Jones sitting at her piano 10' in front of you. Totally cool. Just don't forget to take notes.
BUT...recommend a Nora Jones album for me. I love traditional small-group jazz, Diana Krall, even Rosanne Cash, and 'natural' recordings. The latter means NOT closely mic'd and NOT in my face. I listen to CDs, SACDs, and DVD-As, stereo and MC.

"Come away with me" - One of my favorite test CD's. I can tell a lot about the presentation, detail, bass and richness by listening to this. Also, it really helps to have the pleasing music to use as a test, since you play it over and over and over again.
